Product Description:

1Structure of Seamless Pipe 4 - 12“ API 5L A53 A106 GR.B 20#

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.

Q:What does "DN25 PN16" mean?
Steel pipe DN25, PN16, first of all, for this annotation: pipe DN class, often used in welded pipe, such as welded pipe DN25. PN16 means pressure, that is, 16 kilograms (1.6MPa).
Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
JB/T4709 recommends H10MnSi, but H10MnSi allows a lower value of strength of 430MPa, which does not match the parent material. I think American Standard is selected according to the selection of welding wire ER70S-6 GB ER50-6 wire can guarantee the equivalent strength of parent materials, and Si, Mn content can also guarantee the deoxidation effect, the weld joint is not easy to produce pores.
Q:How can seamless steel tubes be produced?
The material of rolling seamless tube is round tube blank, and the billet is processed by cutting machine to grow about 1 meters, and sent to the furnace by conveyor belt. The billets are heated into a furnace and the temperature is about 1200 degrees celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is a key problem. When the round billet is released, it should be punched through the pressure piercer. The most common punching machine is a cone roll piercer, which has high production efficiency, good product quality, large perforation and expanding diameter, and can be used in various steel grades. After the perforation, the round tube blank has been successively rolled, rolled or squeezed by three rollers.
Q:What is the difference between the stainless steel pipe welded pipe and seamless pipe?
Seamless tube is a strip of steel with a hollow cross section and no seams at all. The general is rolled into a cylindrical tube plate welding.
Q:Stainless steel tube, also known as why tube?
It can be divided into round tube and special-shaped tube according to the cross sectional shapeThe special-shaped tube has a rectangular tube, a rhombus tube, an elliptical tube, six square tubes, eight square tubes, various cross section asymmetric pipes, etc.
Q:Galvanized steel pipe DN100 and SC100
DN is the meaning of "bore", also expressed in water supply and drainageSC is welded steel pipe, generally GB tube, that is, thick walled steel pipe, look at the design requirementsMT refers to the wire tube, usually thin-walled tube, there are KBG and JDG
Q:What is the process of spiral steel tube production?
1. open panel inspection: after the steel plate is opened, the product line is entered, and the ultrasonic examination of the whole plate is carried out first.2., flat milling: through the anvil machine to make the original coiled steel flat, and then through the milling machine on the edge of the steel plate two sides milling, so as to achieve the required plate width, plate edge parallelism and groove shape.
Q:How many meters per ton of steel tube?
Formula of steel tube: (outside diameter wall thickness) * wall thickness *0.02466= per meter weight1000 divided by the weight per metre is how many meters per ton
Q:How can the immersed pipe pile put steel cage into the steel pipe? Which expert to answer?
Immersed tube cast-in-place pile is one of the many types of pile foundations in civil engineering. The immersed tube cast-in-place pile is also called the cast-in-place pile. It is the use of piling equipment, with reinforced concrete pile boots (valve type steel pipe pile shoe) into the soil, pile hole, and then put into the steel skeleton and concrete pouring, then pull out the casing, using vibration extubation of concrete compaction, forming pile needed. Using hammer sinking pile equipment, sinking pipe and pulling pipe pile is called hammer sinking pipe filling pile. It is called vibro sinking pipe cast-in-place pile by vibrator, vibration sinking pipe and pipe pulling pile. In order to improve the quality and carrying capacity of piles, the construction techniques of single shot, double play and reverse insertion are often used in immersed tube cast-in-place piles. Single game (also called a extubation): extubation, every increase of 0.5 ~ 1.0m, 5 ~ 10s vibration, then extubation in 0.5 ~ 1.0m, this is repeated until all pull out; complex play: two singles were continuously in the same pile hole, or according to the needs of the local retapping. Construction, should ensure that two times before and after the immersed tube axis coincide, and in the concrete before the initial coagulation; inverted plug method: steel pipe lifting 0.5m, and then plug 0.3m, so repeated until the pull out.
Q:What does "1.5" steel tube mean?
This is neither an outer diameter nor an inner diameter; it should be related to an English unit at the beginning of the pipeline development; it is usually used to describe galvanized steel pipes; it corresponds to the English units as follows:4, in charge of: 4/8 inches: DN15;• 6 in charge: 6/8 inches: DN20;• 1 inch tube: 1 inches: DN25;• inch two tubes: 1 and 1/4 inches: DN32;• inch half tube: 1 and 1/2 inches: DN40;- inch tube: 2 inches: DN50;• three inch tube: 3 inches: DN80• four inch tube: 4 inches: DN100;
